Answer:
2 cubic feet
Step-by-step explanation:
Convert all the lengths to feet round them to tenths then multiply them.
The answer you have got should be also correct as you have multiplied all the lengths then converted to cubic feet. Since your instructor has said that this is wrong this seems to be the only option remaining.
1 feet = 12 inches

Answer:
y = -2x + 3
Step-by-step explanation:
y = -2x + b
3 = -2(0) + b
3 = 0 + b
3 = b
Answer: g(h(x))=6x +1 and h(g(x)) = 6x+7
Step-by-step explanation: Basically , this is a substitution exercise.
g(h(x)) = g(2x-1) . Now substitute x = 2x-1 in for x in g(x)
hence g(2x-1) = 3(2x-1)+4 = 6x - 3 + 4 = 6x + 1
Similarly : h(g(x)) = h(3x+4) substitute x = 3x+4 in h(x)
hence h(3x+4) = 2(3x + 4 ) - 1 = 6x + 8 - 1 = 6x + 7
